3.2 RabbitLink Firmware
The firmware necessary to operate the RabbitLink with a Rabbit-based target system is loaded at
the factory. This means that after the hardware connections have been made and the network
parameters configured, the RabbitLink is ready to download a program to the local or remote Rab-
bit-based system.
If it is necessary to reload or replace the firmware, the following .bin files are available for
download from the RabbitLink directory that was created when Dynamic C installed. The .bin
files are downloaded to the Rabbitlink using the RFU. The corresponding source files are in the
same directory and may be used instead by compiling them to the RabbitLink using Dynamic C.
•
CLEAR_PARAM.BIN —Binary image to reset the network configuration parameters of the
RabbitLink board (stored on the second flash) to default values. This binary file is used to
reset the serial port if its operation has become undefined.
•
DOWNLOAD.BIN
—RabbitLink firmware binary image.
The RabbitLink firmware version must be compatible with the version of Dynamic C that is used
to download applications to the target that is connected to the RabbitLink (see Table 2). The com-
panion CD in the RabbitLink Tool Kit contains versions 1.00, 2.00 and 2.05 of the firmware.
3.2.1 Downloading Firmware to the RabbitLink
Follow these steps to reload the firmware or to reset the RabbitLink serial port.
1. Connect the RabbitLink board to your PC as shown in Figure 3.2.1-1 with the
PROG
connector
on the programming cable connected to the PROG IN header of the RabbitLink board.

2. Use the RFU version 2.0 or later to load the
DOWNLOAD.BIN
firmware or the
CLEAR_PARAM.BIN
binary image onto the RabbitLink board.
3. Disconnect the programming cable.
4. Unplug the power supply, then plug the power supply back in. This resets the RabbitLink from
Program Mode to Run Mode.
